The use of Monel Pipes and Tubes is chosen in cases when a project requires a higher level of durability and corrosion resistance in comparison with the standard nickel alloys or stainless steel. The engineers working in the marine, oil, and gas and chemical processing settings have known that Monel 400 Pipes and Tubes have performed well in seawater systems, heat exchangers or corrosive chemical lines whereas Monel K500 Pipes offer higher mechanical strength needed in rotating machinery, pump shafts and pressure-driven systems.
Being a trusted Monel pipe supplier and manufacturer, Stellar Alloys is guided by a technical and quality-focused business principle in dealing with high-nickel alloys. We provide Monel 400 pipe, Monel K500 pipe, Monel 400 tube and Monel K500 tube in seamless and welded versions manufactured to ASTM B165, ASTM B725, and similar specifications.

Monel 400 and Monel K 500 Pipes and Tubes find application in the situations where the components are supposed to be strong and resistant to corrosion in highly stressful environments, with variable temperatures, as well as with exposure to aggressive media. Stellar Alloys as a manufacturer of Monel pipes, a supplier and stockist, offers the materials that are appropriately applicable in demanding use in the marine engineering, chemical plants, refineries, offshore platforms, and heat exchanger systems. Monel 400 Pipes (UNS N04400) exhibit stability with rapid flowing seawater, steam and neutral or mildly acidic solution and Monel K500 Pipes (UNS N05500) are more mechanically strong and hard enough to be a dependable pump shaft, valve parts and rotating apparatus.
We also have Monel seamless pipe, Monel welded pipe, Alloy 400 tubing and K500 tubing, which are all produced under ASTM B165 and ASTM B725. These standards help to maintain dimensional accuracy in every individual pipe thereby, providing both high temperature and low temperature service with a consistent performance. Monel alloys maintain strength at temperatures below zero degrees and do not crack when exposed to stressful conditions in the environment of high pressure, that is why they are widely used in the marine sphere and corrosive processing lines.
Material Test Reports and complete traceability are provided with every batch to aid in quality assurance needs. Being a reliable stockist in Monel pipes, we assist procurement teams in choosing the right grade or size and schedule to suit the specifications of the project. Do you need a well-established corrosion resistance, temperature stability or increased tensile strength, our technical experts can help you to determine the best Monel 400 or Monel K500 product that will be used in the long-run in industry.
Monel Alloys 400 vs K500: Key Differences at a Glance (Comparison Table)
Despite the fact that the Monel 400 and Monel K500 share an excellent resistance to reducing media, sea and stress-corrosion cracking, their mechanical properties and subsequent applications are polar opposites of each other. Your choice of material, high standard of strength and the anti-galling will be the key considerations; Monel K500 will be superior in these aspects due to the ability to age harden. The essence of the differences between these two workhorse nickel-copper alloys, used in piping and tubing, are presented in the following table.
